: I have an engine which was rebuilt last year as part of my frame off resoration. The motor has only 100 miles on it and is still tight. The engine runs at idle very well. However when you start to run it out on the highway it seems to "fall off"
: after 40 MPH. I have changed the coil, condensor, I have run 3 different carbs and also double checked the manifold and carb to intake gasket. I've loosened the gas cap to make sure it doesn't have a vacum etc. I've not checked the valve clearance yet...but don't think that is the problem.
Long way from being an expert on fuel problems.
could it be that the extra weight of the fuel in the tank is causing extra pressure on the gas lines/carb? This extra pressure may be able to force more gas pass some obstruction/crud in the lines or filter.Sounds like you have a blocked fuel filter.Also you might want to check float level.If the level is not high enough, could run ok at idle, but not when more power is required.

: Last night I noticed that when the car is FULL of fuel the problem nearly goes away but when the tank gets to 1/4
: the problem starts to return ?What am I missing?
